The Province of Bali has its own flag. It is of a mere light saffron background charged with the province's coat of arms. Please note that although I have no information regarding the status of this flag, I strongly suppose that it is a government flag, since---as other Indonesian provincial flags---it is displayed inside the governor's office and local parliament building. It is clearly not a de facto civil flag.

The face on the coat of arms is a highly stylized 'barong', a traditional mask in Bali. Whenever you go to Bali, barongs are everywhere. The base ornaments consist of a lotus with two leaves and two kipas (hand fans). Together with the temple, they show Bali's proudly ancient culture.
